36 Claims.

This invention relates to shoe machines and is herein illustrated in its application to machines for use in the manufacture of prewelt shoes. Machines of the type herein illustrated operate to force the forepart of a last into the forepart of a prewelt upper, then to last the upper by means of wiper plates constructed and arranged to operate within the welt crease, and finally, to hold the upper in lasted position by means of the wiper plates while a sole is attached to the welt. A machine of this type is illustrated in United States Letters Patent No. 2,042,518, granted June 2, 1936, on an application of Karl Engel.

It is an object of the present invention to provide a machine of this type which is inexpensive to manufacture and which permits a high rate of production while affording greater accuracy and uniformity of lasting than heretofore obtained in machines of this type.

With a view to affording a high degree of accuracy and uniformity in the lasting of uppers by machine, this invention provides lasting wipers arranged for bodily rectilinear closing movements havingpredetermined components lengthwise and widthwise of a shoe in the machine, the directions of closing movements of said wipers changing at a predetermined point intheir operation in order to provide two stages of wiper'movement for a purpose now to be eXplained. During the first stage of their closing movement, the wipers are advanced in paths so arranged as to afford a short, direct initial movement into a position in which their wiping edges define an outline having the same contained in order that thewipers may operate accurately and uniformly on a run of sizes of shoes. This construction permits the use of a minimum number of wipers. For example, only four sets of wipers are required for lasting shoes from infants size 1 to 10%, each set of wipers operating on two and one-half sizes. In order to maintain a predetermined orientation of the wipers relatively to each other during their operation, the wipers are interconnected by means herein illustrated as dowels which slide in suitable bores in the wiper carriers. In accordance with a further feature of the invention, the wipers are held on their carriers by means permitting convenient and, rapid interchange of Wipers, said means including a hold-down member which is out of registration with the wipers when the wipers are retracted and therefore need not be moved to permit removal of the wipers. The wipers are located on the carriers, without securing them to the carriers, by means herein illustrated as pins which enter suitable holes provided in the wipers.

For supporting the toe portion of a prewelt upper, a work support is arranged to engage the upper in the welt crease and hold the welted margin slightly above position to receive the lasting wipers in order to facilitate movement of the wipers into a position beneath the welt, and the machine, in accordance with a further feature of the invention, is provided with-means operable at the will of the operator to move the work support downwardly to bring the upper into position to receive the wipers. For forcing the forepart of a last into the forepart of an upper supported by its welted margin, the illustrated machine is provided with means herein illustrated as a last depressor which operates automatically during the downward movement of the work support to move the last downwardly with the upper, thus preventing movement of the last out of the upper. As herein illustrated, the depressor comprises a last-engaging member movably mounted in a carrier in which'is also mounted means for yieldingly pressing said member against the last.

For pressing the rear part of the last upwardly against the overlasted margin of the upper and supporting it during the sole-attaching operation, the illustrated machine is provided with a last support, a wedge for applying upward pressure to said support,-and a toggle which may alternatively be advanced bodily with the wedge or actuated to apply heavy pressure to the wedge, In the operation of the machine, the wedge and toggle are advanced asaunit to lift the work support until it meets resistance, whereupon the toggle is straightened to advance the wedge forcibly and thus to cause the work support to press'the last upwardly against the,

overlasted margin of the upper. In order to permit adjustment of the last support lengthwise and widthwise of the shoe, the last support and the pressure-applying assembly are mounted in a carriage arranged for adjustive movement lengthwise and widthwise ofthe shoe. It will be understood that the last-depressing means and the means for applying upward pressure to the last are not limited in their utility to their illustrated embodiment in a prewelt shoe machine, but are applicable to machines for oper ating on other types of shoes and to machines which perform operations other than lasting operations.

These and other features of the invention will now be described with reference to the accompanying drawings and pointed out in the appended claims.

Fig. 6 is a sectional view taken on the line VI-VI of Fi 4; and

Fig. '7 is a perspective view of the toe supporting means.

Referring to Fig. 1, the illustrated machine comprises a frame Ill adapted to rest on a bench or other suitable support, the top of said frame being provided with a suitable shoe-receiving opening. Mounted for rotary movement on a top plate l2 (Figs. 2 and 3) and guided by the arcuate edge faces of guide plates I3 is a flat ring which in the illustrated machine comprises a metal top plate l4 and a wooden base plate I 5 within the central openings of which the shoe to be operated upon is positioned. The illustrated machine is adapted to operate only on infants shoes and childrens shoes of the smaller sizes. In order to provide sufiicient room within the ring for the largest size shoe on which the machine is intended to operate, the inner margin of the ring is cut away at [6 to provide clearance for the rear part of the shoe. Mounted on the upper surfaces of the plates l3 and the ring [4, which surfaces, as shown in Fig. 3, lie in a common plane, are four wiper carriers l8 (Figs. 2 and 3) the inner edge faces of which provide a generally rectangular shoe-receiving opening. The wiper carriers in their movements relatively to each other are guided in rectilinear paths by dowels 20 (Fig. 2) mounted in horizontal bores extending into the carriers at right angles to their edge faces. These dowels cause the wipers to close in unison and at a common rate of speed, and they also serve to maintain a suitable arrangement of the carriers relatively to each other such that the wiping edges of the wipers will be in alinement during the lasting operation. Two forepart-lasting wipers 22 and two rearpart-lasting wipers 24 rest on the upper surfaces of the wiper carriers and are located relatively to the carriers by pins 26 (Figs. 1 and 5) projecting upwardly from the carriers through suitable holes in the wipers. For holding the wipers against upward movement away from their carriers during the lasting operation, hold-down plates 28 are secured to the end walls of the frame II] by clamping screws 30 which extend through transverse slots 32 in the hold-down plates. To assist in holding the wiper plates against upward movement away from the carriers, two hold-down plates 34, only one of which is shown in the drawings, are secured to the bottom of the horizontal portions of brackets 36 secured to the frame and extending inwardly over the adjacent margins of the wipers at opposite sides of the shoe-receiving opening, each hold-down plate being adjustable vertically by means of a screw 38 mounted in th end of the bracket 36. Referring to Fig. 2, it will be seen that the illustrated hold-down plate 34 is out of registration with the wipers when the wipers are fully retracted and when it is desired to remove the wipers from the machine, all that is required is to turn the screws 30 sufficiently to permit the hold-down plates 28 to slide outwardly away from the wiper plates so that the wiper plates may be lifted off their carriers. For guiding and directing the movements of the wipers relatively to a shoe in the machine, each wiper carrier is provided with two pins 40 (Fig. 2) which extend downwardly from the wiper carrier into angular cam slots 42 in diagonal plates 44 mounted in grooves in the top of the frame. These cam slots are identical in construction and arrangement and extend from their outer extremities in paths radial to the path of movement of the ring l4 and are arranged at angles of 45 degrees to the longitudinal median line of a shoe in the machine. The inner portions of the slots 42 are arranged at an obtuse angle to their outer portions and extend toward the center of the machine in parallel paths which converge toward the longitudinal median line of a shoe in the machine at angles of approximately 13 degrees. Thus, it will be seen that the wipers in the course of their inward movements travel in rectilinear paths the directions of which change at predetermined points thus providing two stages of movement of the wipers in the first of which their movement has equal components lengthwise and widthwise of a shoe in the machine and in the second of which their components of movement lengthwise of the shoe are much greater than their components of movement widthwise of the shoe. When the wipers have advanced to the point where their paths of movement change, their wiping edges define an outline having the same configuration as the contour of the sole portion of a shoe on which the wipers are intended to operate. In operating upon the largest size in the run of sizes for which the wipers are provided, the wiping operation is completedwhen the wipers come to the limit of their 45-degree motion. It will be understood that in operating upon the largest size in the run, the wipers in their closed position will be separated from each other at opposite sides of the shank portion of the shoe approximately three-quarters of an inch. If desired, these portions, which the wipers do not reach, may be lasted by hand, for example, by means of a boning tool; but ordinarily, it will not be found necessary to do any hand lasting since the comparative rigidity of the welt will usually insure a proper lasting of these portions of the upper. In operating on the smaller sizes in the run, the wipers enter the second stage of their movement, the extent of which varies in accordance with the size of the shoe being operated upon. In operating on the smallest size in the run the wipers come into abutting relation to to the upper.

.86 in thebottom ofnthev block 16', said T groove each other both at the ends of the sho and at the sides of the shoe upon completion of their closing movement and provide a continuous support for the outwardly extending margin of the welt. During the second stage of their movement the configuration defined by the wiping edges of the wipers at the end of their -degree movement is maintained in order that the wipers may operate accurately and uniformly on all sizes of shoes within the run. This result is accomplished by arranging the inner portions of the slots 42 at an angle of 13 degrees to a line parallel to the longitudinal median line of the shoe. It has been found that this arrangement of the slots 42 produces a Wiper motion in which the ratio;

of movement lengthwise of the shoe to .movement widthwise of the shoe corresponds to the ratio of the diiference in length to the difference in width from one size shoe to another. The difference in length from size to size is one-third of an:

inch and the diiference in width from size to size is one-twelfth of an inch, and, accordingly, thev structed and arranged relatively to the wiper carriers that the wipers advance rapidly during thefirst stage of their movement when the shoe offers no resistance to their movement and advance slowly after the wipers have entered the welt crease of the upper in order that the lasting operation may be effectedwith a minimum of exertion on the part of the operator by reason of the ratio of the movement of the actuating means to the movement of the wipers. For actuating the ring I4,'a cam plate (Fig. 1) is se-g cured to a rock shaft 52 provided with a hand having'an open end. atthe curved end of the block I6 and terminating in an end wall 88 which engages the end of the plate 84 to locate the toesupporting assembly lengthwise of a shoe in the machine. The shaft 82 is sliclably mounted in a hollow'post 90 fixed to the base of the machine.

I When the machine is at rest, the toe-supporting assembly is at the limit of its .upward movement as seen in Fig; 3 in which position the fingers 15 hold the welted margin of the upper at its toe end above the-plane of the forepart wipers 22. In

this position the toe-supporting assembly is supported by a toggle which operates in a recess in the post 90, said toggle comprising an upper link 92 pivotally mounted in the lower end portion lever 54', said cam plate having a groove 56 in -which travels a cam roll at one end of a bell crank lever 58 freely mounted ona shaft 60 and connected by a link 62 to a slide 64 which carries inatransverse groove 06 a block 68 swiveled on a pin I0 extending downwardly from the ring I4.

For supporting the toe'portion of a prewelt upper; for examplathe upper I2, illustrated in Fig.

3, the machine is provided with a work-support-r ing plate I4 (Figs. 3 and 7) having upwardly extending fingers I5 theends of which enter the welt crease of the upper and support the upper by engagement with the seam securing the'welt The plate I4 is bent around a block '16, the peripheral contour of which'corresponds generally to the outline of the toe portion of a shoe, said plate being secured to the curved edge face of the block 10 by a screw I8, and to the opposite sides of the block by two screws 80 extending" through horizontal slots at opposite end portions of the plate. The side portions of the plate I4 spring outwardly against the heads of the screws 80 and by turning said screws, the

plate may be adjusted to arrange the upper supporting fingers to support different sizes of uppers. The block 16' is supported on a vertically sliding shaft 82 which has secured to its upper end a plate 34 which is T-shaped in cross'section widthwise of the shoe and fits into a T-groove of the shaft82 and a lower link 94 which is secured tothe rock shaft 60 by a pin 98 which is extended to provide ananchorage for a spring I00 which holds the toggle in straightened position. For breaking the toggle to move the toesupporting assembly downwardly thereby to bring the toe portion of the shoe into position to be operated upon by the forepart Wipers, the rock shaft 60 isprovided with a hand lever I02 (Fig. 1). As the forepart of theupper moves downwardly with the toe-supporting, assembly, the welt I04 engages the margin of the forepart wipers and its downward movement is arrested by the wipers while the downward movement of the work-supporting assembly continues to carry the fingers I5 out of. alinement with the forepart wipers'to provide clearance for their operation. The block I6 togetherwith the plate I4 is-readily removable from the plate 84 by moving the block to the left, as seen in Fig. 3, when there is no shoe in, the machine, the plate .'I4, being held against misplacement by the shoe itself during the operation of-the machine. The machine is provided with two such removable toe-supporting units, one for right and the other for left shoes. It is not necessary to providea plurality of toesupporting units for different sizes of shoes since the toe-supporting plate I4 is adjustable widthwise by turning the screws 80.

The prewelt'upper, when it ispresented to the illustrated machine, is assembled on the rear part of a last and preferably secured in assembled position by a'tack I06 driven through the rear part of the upper and into the last, but the" forepart of the last projects outwardly through the bottom opening of theupper and must be forced into the upper preliminary to the lasting operation. For forcing the forepart of the last into the upper while the toe portion of the upper is supported by fingers I5, the' illustrated inachine is provided with a last depressor, illustrated in Fig. '1, comprising a slide I00 mounted in a vertical opening in an arm I-I0 mounted to swing on a vertical axis to carry thedepressor assembly to and from operating position. The slide I08 has a longitudinal-boreextending upwardly from I its lower end in which is mounted a plunger I I2 the lower end of which hasa flat head I I4 which engages the toe portion of a last, for example,

the last III1 illustrated inFigs. 3 and 4. The plunger I I2 is backed up byaspring I I8 mounted in thesocket in' the slide I08, the plunger being retained within the socket by a pin I20. extending outwardly from the plunger through a longituidinal'slot 522 provided in the slide I08. For operating the depressor; there is provideda toggle mechanism comprising a link I24 pivoted in an upward extension I26 ofthe arm IIO,- said link havinga handle I28 for operating the toggle, andlower toggle links. I30 connecting the upper link to the upper portion of the slide I08. A pin I32 in the upward extension I26 of the arm determines the straightened position of the toggle. In the operation of the last depressing assembly, the slide I08 moves downwardly with theplunger II2 forcing the forepart of the last into the supported upper and after the last has come to the limit of its downward movement, the slide I08 continues its downward movement until the toggle has'com'e into its straightened position, illustrated in Fig. 1, compressing the spring H8, as shown in Fig. 3. During the subsequent downward movement of the toe-supporting assembly from its position in Fig. 3 to its position in Fig. 4, the spring H8 expands to maintain a sufficient pressure against the plunger 2 to hold the last in a proper position within the toe portion of the upper for the subsequent lasting operation. The depressor assembly remains in operative position until the completion of the lasting operation whereupon the handle I28 is moved upwardly to break the toggle and lift the depressor from the last bottom, whereupon the arm I I is swung into arernote position by a torsion spring I34 (Fig. 1).

After the upper has been lasted, the wipers 22 and 24 remain in their advanced positions to support the outward extension of the welt I04 while a sole is cement attached to the welt. It is important that the last be held. firmly against the overlasted margins of the welt and upper during the cement attachment of the sole to the welt. At the toe end of the shoe, the tension of the upper itself is sufiicient to hold the last firmly against the overlasted margins. In. order to apply upward pressure to the rear part of the last to bring it forcibly against the overlasted margin of the upper and hold it rigidly in position while a sole is attached, the illustrated machine is provided with a work-support herein illustrated as a square post I36 slidably mounted in a square hole in a carriage I38 and having at its upper end a last pin I40 which is received within the last pin hole in the rear part 'of the last. The carriage I30 is mounted for longitudinal sliding movement in a groove I42 in a carriage support herein illustrated as a flat plate I44 which rests on the base of the frame and is fulcrumed thereto at I46 to permit swinging movement of the carriage for adjustment of the post I36 widthwise of the shoe. For moving the carriage I38 longitudinally in the support I44, a short arm I66 is secured to a shaft I68 and bifurcated at its lower end for engagement with a ball headed stud I extending upwardly from the carriage. The arm I66 is operated by a hand lever I12 formed by bending the outer end portion of the shaft I68 into the position illustrated in Fig. 1. For applying upward pressure to the post I36, a wedge I48 mounted for sliding movement between the walls I50 (Fig. 6) of the carriage acts against the inclined bottom face of the post I36 as the wedge is moved to the right as seen in Fig. 4. For operating the wedge, the illustrated machine is provided with a toggle mechanism comprising a pair of links I 52 (Figs. 4 and 6) pivoted to a reduced extension I54 of the wedge and pivoted at their opposite ends to a toggle link I56 having a handle I58. Swiveled at opposite sides of the toggle link I56 are pawls I60 which are confined between the toggle link and the walls I62 (Fig. 6) of the carriage I38 and. are provided with teeth which engage ratchet plates I64 secured to the walls I62 of the carriage, one r of said ratchet plates being illustrated in Fig. 4. When the toggle link I56 is resting against the bottom of the carriage I38, the teeth of the pawls I60 are out of engagement with the ratchet plates I64 and the toggle and the wedge may be slidably advanced as a unit with the toggle in its broken position, as illustratedv in Fig. 3, to lift the post I36 until it meets resistance, whereupon the handle IE8 is lifted, bringing the pawls into engagement with the ratchet plates and straightening the toggle to advance the wedge forcibly against the end face of the post and move the post upwardly with sufficient force to press the bottomof the last hard against the overlasted margin of the upper. If desired, the operation of the toggle may be repeated to increase the pressure of the last against the upper, the frictional engagement of the wedge with the end face ofthe post I36 being sufiicient to hold the wedge in position while the pawls are being advanced into a new position on the ratchet plates. It will be seen that the broken position of the toggle, as shown .in Fig. 3, is determined by the engagement of the diagonal surface at the right end of the toggle link I56 with the top of the toggle-receiving chamber in the carriage I38.

In the operation of the illustrated machine, a prewelt upper, the rear part of which has been mounted on a last and attached thereto by the back-seam tack I66 (Fig. 3) is positioned in the machine, the last being mounted on the last pin Hi6 while the upper is positioned on the toe-supporting fingers I6. At this time the forepart of the last projects upwardly somewhat through the bottom opening of the upper. To bring the forepart of the last down into position for the lasting operation, the last-depressing assembly is operated by swinging the handle I28 (Fig. 1) downwardly into its position in Fig. 1, straightening the toggle I24, I30 and forcing the plunger I I2 downwardly against the last. The wipers are then advanced until they are arrested by the engagement of the forepart wipers 22 with the toe-supporting fingers I5 (Fig. 3) whereupon the toe-supporting assembly is moved downwardly bringing the welt at the forepart of the upper into engagement with the wipers 22. the downward movement of the toe-supporting assembly, the spring H8 in the depressor assembly maintains suiiicient pressure of the plunger H2 against the last to hold the last in position on the upper. By supporting the forepart of the upper above the plane of the forepart lasting wipers 42, the initial advancement of said wipers into a position beneath the welt I04 is facilitated and accidental engagement of the'wipers with the sole-attaching face of the welt is obviated. After the toe-supporting assembly has been moved downwardly into its position illustrated in Fig. 4, the wipers 22 and 24 are further advanced into their positions illustrated in Fig. 4 to complete the lasting operation. After the lasting has been completed, the wedge I48 is moved to the right, as seen in Fig. 4, to force the post I36 upwardly in order to press the overlasted margin of the upper firmly against the wipers, and while the last is supported by said post and the outward extension of the welt I04 is supported by the wipers, a filler (not shown) is positioned on the last bottom in the space enclosed by the adjacent edge faces ofthe welt and upper and a sole, previously treated with cement, is applied to the filler and the welt which have likewise been treated with cement. The sole During.

be bonded to the. Walt and-the filler in any suitable manner, for example, by pounding it with a hammer which is faced with rubber or other suitable material to prevent objectionably marking the sole. tached, the wipers are fully retracted, leaving the shoe free to be removedfromthe machine.
